In South Africa, the National Building Regulations (SANS 10400-XA: Energy Usage in Buildings) makes it compulsory for all new buildings to be insulated as of November 2011.
A traditional pitched roof allows for good water drainage. However, when it comes to flat roofing, water build-up on the roofing itself is a normal structural issue.
At the height of summer, the average metal roof can reach temperatures in excess of 60°C.
The majority of common ventilation systems cannot effectively manage these conditions and fail to maintain favourable temperatures for chicken and pig farming.
Calculating the energy costs within a building can be a complex process with many influencing factors.
In this article, we will be explaining some of the benefits of using spray foam insulation to minimise your energy costs.
